It seems Microsoft is increasing the amount of space its operating system takes up with things rising from 16GB to 32GB.

This means you must have that amount of space clear on your PC before you can install the changes.

One of the reasons that Microsoft has increased this size is due to a new feature called reserved storage which keeps 7GB free to be used for updates and things such as temporary files.

Discussing the Windows 10 change, Microsoft said: "Starting with the next major update we’re making a few changes to how Windows 10 manages disk space.

“Through reserved storage, some disk space will be set aside to be used by updates, apps, temporary files, and system caches.

"Our goal is to improve the day-to-day function of your PC by ensuring critical OS functions always have access to disk space. Without reserved storage, if a user almost fills up her or his storage, several Windows and application scenarios become unreliable."

Microsoft has insisted the result of the extra storage being used by Windows 10 will result in a smoother user experience overall.

However, that won’t help those who have laptops and desktop PCs with limited storage.

It seems a bug in the software is meaning some customers may struggle to install this upgrade with a message appearing on the screen that reads, "This PC can't be upgraded to Windows 10".

According to Microsoft, this issue appears when a computer is using an external USB device or SD memory card.

In a post on its support website, the US firm said: "Inappropriate drive reassignment can occur on Windows 10-based computers that have an external USB device or SD memory card attached during the installation of the May 2019 update.

"For this reason, these computers are currently blocked from receiving the May 2019 Update. This generates the error message that is mentioned in the "Symptoms" section if the upgrade is tried again on an affected computer."
